what's the advantage of a system like that? because it has a low VFoV and is very big and expensive.
I can imagine only two Image Quality over other mirror solutions, and live stitching/no parallax over other multicamera systems.

It shows another option, of having several cameras pointing up into mirrors. The
mirror creates a upside pyramid. The pyramid is hollow and allows a single
camera can be placed at the NPP to capture the zenith.

Nice video, but why they are claiming 360x360 (which in any case should be 360x180 as much)? From what I can see there s only 360x90, and if you put 2 pyramids

Nice video, but why they are claiming 360x360 (which in any case should be 360x180 as much)?
From what I can see there's only 360x90, and if you put 2 pyramids then you will get two big gaps in nadir and zenith.
Do you know how to get 360x180 with these flat mirrors?

There will always be one whole where the camera rig is attached to the tripod.
For the zenith placing an up pointing camera in the middle of the four pointing
into the pyramid would close off the zenith although there would be some
parallax error.

Yes I saw the design with the camera inside the pyramid (I don t understand why you think it has error parallax if it s exactly on the same virtual viewpoint

Yes I saw the design with the camera inside the pyramid (I don't understand why you think it has error parallax if it's exactly on the same "virtual viewpoint" of the other cameras).
But how can it cover the full zenith hole?
Can you cover more than Vfov = 90º with the 4 mirrors?
I couldn't find any 360x180 panorama made with fullview :(
